Plugins allow for easy extensibility and customization of the framework.
Plugins are classes. The actual class definition will vary based on the component -- you may need to implement this interface, but the fact remains that the plugin is itself a class.
A plugin could be loaded into Yaf by using Yaf_Dispatcher::registerPlugin(), after registering, All the methods which the plugin implemented according to this interface, will be called at the proper time.
Beispiel #1 Plugin example
<?php
/* bootstrap class should be defined under ./application/Bootstrap.php */
class Bootstrap extends Yaf_Bootstrap_Abstract {
public function _initPlugin(Yaf_Dispatcher $dispatcher) {
/* register a plugin */
$dispatcher->registerPlugin(new TestPlugin());
}
}
/* plugin class should be placed under ./application/plugins/ */
class TestPlugin extends Yaf_Plugin_Abstract {
public function routerStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* before router
in this hook, user can do some url rewrite */
var_dump("routerStartup");
}
public function routerShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* router complete
in this hook, user can do login check */
var_dump("routerShutdown");
}
public function dispatchLoopStartup(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("dispatchLoopStartup");
}
public function preDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("preDispatch");
}
public function postDispatch(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
var_dump("postDispatch");
}
public function dispatchLoopShutdown(Yaf_Request_Abstract $request, Yaf_Response_Abstract $response) {
/* final hook
in this hook user can do logging or implement layout */
var_dump("dispatchLoopShutdown");
}
}
Class IndexController extends Yaf_Controller_Abstract {
public function indexAction() {
return FALSE; //prevent rendering
}
}
$config = array(
"application" => array(
"directory" => dirname(__FILE__) . "/application/",
),
);
$app = new Yaf_Application($config);
$app->bootstrap()->run();
?>
